' This invention relates to wire hose clamps and more particularly totools' for applying such clamps. c I

The object of the invention is to provide a tool for applying wire hoseclamps which is cheap, speedy and durable and which will so connect theclamp with the hose that "no open spot will beleft beneath the lockforleakage to occur.

In carrying out these objects, the invention is susceptible of a widerange of modification without departing "from the spirit or sacrificingany of the advantages of the claimed invention; there being shown in'thedrawings for illustrative purposes a preferred and practical form, inwhich:

Figure 1 is a perspective showing'this tool in the position it assumeswhen being ap plied operation, the hose being shown in transversesection; and b f Fig. 3 is asimilar viewwith the -too11 in the positionit assumes when it has completed or just time for the completion of theclamping action the hose being shown in section.

V While this tool is shown for clamping a hose to a nipple by means of awire'clamp obviouslyit may be used in connectionwith such a clampforconnecting any other two I objects to whichit may be adapted. The

nipple 1 to which the hose 2 is shown engaged" is inserted in the hoseand the wire clamp 3 which is made in theform of a wire loop encirclingthe hose with its two ends [4: passed through the looped portion anddesigned to be drawn taut for clampingly connecting the hose to thenipple. To accomplish this clamping and effectively connect thejtwo Imembers this tool '10 is designed and itcomprises two levers'll and 12constructed of strain resisting strips of metal each of which is curvedat one end similar to a sled shoe as shown at 13 and these'curvedendseach are provided with laterally spaced apertures 1a and 15'throughwhich "the ends4 ofthe' wire clamp are designed to-be passedrasis shown clearly in Fig. 1. 1

tion with a longitudinally"eiztending slot-like clamp tightly'aroundithe enclosed hose.

Fig. 2 is a side elevation of the tooland clamp in position ready forthe clamping The lever 12 is provided at its curved porf claimed; j 1

opening 16' to permit the pa'ssing' therethrough ofthe ends ofthe wireclamp when the two levers are locked'together as shown in Fig.8 to drawthe loop'form-iiig' the w Inthe operation of this'toolit-WiIlb-eiunderstoodkthat: the 'lever12 is first engag'ed V with thewire ends L of the clamp as is shown.

in Fig. 1 and then above this lever the lever Z11" 11 is engaged withthe ends the concave porj tions-of the levers facing each other,itgbeing of course understood that the clamp has I been looped aroundthe hose in the form of a nooseybeforethis' tool is engaged therever 12with their rocking or convexffaces in engagement as shown at'l'i' inFig. 3,thecontacting curved portions of the levers operating as v afulcrum for lever 11-.which when forced down 'draws the wire ends 4tightly through the loop of the clamp and; the ,free- 7 with. The leversare then slid down on the), I vwire ends tuntil they nearly contact thehose "and then the lever '11 is swung over-onto leends 4 of the wirewill pass through the open-i ing 13 in lever 12 and be out of thewayduring' the clamping ope-ration.

After the clamp has been securely locked onthe hose the levers'ofqcourse'are disen gaged from the ends at by slipping sa'id' ends Iout'of the aperturesl and 15 and" the bent surrounding objects f 1 Itwill thusbe seen that thi siiriplflittig I and will quickly andeffectively'bend the membersthereof to. secure the parts of the hose'orother object. andthe part towhich itis to beisecured. 1 'Without'further description it is thought i that the features and advantages ofthe in vention will be readily apparent to-those skilled in the art, andit will, 'off-course be" {end may be moreiclosely forced-against the t jv I a hose if-desired to preventthem]engagi v tool which may be cheaplyconstructed is 9 easily applicable to the ordinary wire 'clarn'pvunderstood that changes in the torm, ,pro-
